6. Registration Statement.

For purposes of this Clause 6, the Sale Shares included in the Registration Statement shall include, as of any date of determination, the Sale Shares and any other equity security of Pubco issued or issuable with respect to the Sale Shares by way of share division, stock split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event or otherwise.

6.1 Pubco agrees that, within thirty (30) calendar days after the consummation of the Transactions (the “Filing Date”), Pubco will file with the Commission (at Pubco’s sole cost and expense) a registration statement (the “Registration Statement”) registering the resale of the Sale Shares (the “Registrable Securities”), and Pubco shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof, but not later than the earlier of (i) sixty (60) calendar days following the consummation of the Transactions, (ii) ninety (90) calendar days following the consummation of the Transactions if the Commission notifies Pubco that it will “review” the Registration Statement or (iii) ten (10) Business Days after the date Pubco is notified (orally or in writing, whichever is earlier) by the Commission that the Registration Statement will not be “reviewed” or will not be subject to further review (such date, the “Effectiveness Date”); provided, however, that Pubco’s obligations to include the Registrable Securities in the Registration Statement are contingent upon a Seller (as applicable) furnishing a completed and executed selling shareholder’s questionnaire in customary form to Pubco that contains the information required by the Commission rules for a Registration Statement regarding such Seller, the securities of Pubco held by such Seller and the intended method of disposition of the Registrable Securities to effect the registration of the Registrable Securities, and such Seller shall execute such documents in connection with such registration as Pubco may reasonably request that are customary of a selling shareholder in similar situations, including providing that Pubco shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement as permitted hereunder; provided that such Seller shall not in connection with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to transfer the Registrable Securities (excluding any such restrictions under the Lock-Up Agreement). Any failure by Pubco to file the Registration Statement by the Filing Date or to effect such Registration Statement by the Effectiveness Date shall not otherwise relieve Pubco of its obligations to file or effect the Registration Statement as set forth above in this Clause 6. Unless required under applicable laws and Commission rules, in no event shall a Seller be identified as a statutory underwriter in the Registration Statement; provided, that if a Seller is required to be so identified as a statutory underwriter in the Registration Statement, such Seller will have an opportunity to withdraw its Sale Shares from the Registration Statement.

6.2 In the case of registration effected by Pubco pursuant to this Deed, Pubco shall, upon reasonable request, inform the Seller as to the status of such registration. At its expense Pubco shall:

(a) except for such times as Pubco is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under state securities laws which Pubco determines to obtain, continuously effective with respect to such Seller, and to keep the applicable Registration Statement or any subsequent shelf registration statement free of any material misstatements or omissions, until the earlier of the following: (i) such Seller ceases to hold any Registrable Securities, (ii) the date all Registrable Securities held by such Seller may be sold without restriction under Rule 144, including without limitation, any volume and manner of sale restrictions which may be applicable to affiliates under Rule 144 and without the requirement for Pubco to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable), and (iii) two (2) years from the Effectiveness Date;

7

(b) advise each Seller as promptly as practicable, but in any event within five (5) Business Days:

(i) when the Registration Statement or any post-effective amendment thereto has become effective;

(ii) after it shall receive notice or obtain knowledge thereof, of the issuance by the Commission of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose;

(iii) of the receipt by Pubco of any notification with respect to the suspension of the qualification of the Registrable Securities included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

(iv) subject to the provisions in this Deed, of the occurrence of any event that requires the making of any changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading.

Notwithstanding anything to the contrary set forth herein, Pubco shall not, when so advising such Seller of such events, provide such Seller with any material, nonpublic information regarding Pubco other than to the extent that providing notice to such Seller of the occurrence of the events listed in (i) through (iv) of this Clause 6.2(b) constitutes material, nonpublic information regarding Pubco;

(c) use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable;

(d) upon the occurrence of any event contemplated in Clause 6.2(b), except for such times as Pubco is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of the Registration Statement, Pubco shall use its commercially reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Registrable Securities included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(e) use its commercially reasonable efforts to cause all Sale Shares to be listed on each securities exchange or market, if any, on which the Exchange Shares are then listed;

(f) use its commercially reasonable efforts to allow a Seller (as applicable) to review disclosure regarding such Seller in the Registration Statement and consider in good faith proposed revisions from such Seller; and

8

(g) use its commercially reasonable efforts to (x) take all other steps reasonably necessary to effect the registration of the Sale Shares contemplated herein and (y) take such further action as such Seller may reasonably request, all to the extent required from time to time to enable such Seller to sell such Seller’s Sale Shares held by such Seller without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule promulgated thereafter by the Commission, to the extent that such rule or such successor rule is available to Pubco).

6.3 Notwithstanding anything to the contrary in this Deed, if the Commission prevents Pubco from including in the Registration Statement any or all of Pubco Shares due to limitations on the use of Rule 415 of the Securities Act for the resale of Exchange Shares by a Seller (as applicable), the Registration Statement shall register for resale such number of Exchange Shares which is equal to the maximum number of Exchange Shares as is permitted by the Commission. In such event, the number of Exchange Shares to be registered for each selling shareholder named in the Registration Statement shall be reduced pro rata among all such selling shareholder and as promptly as practicable after being permitted to register additional Exchange Shares under Rule 415 under the Securities Act, Pubco shall use commercially reasonable efforts to amend the Registration Statement or file a new Registration Statement to register such Exchange Shares not included in the initial Registration Statement.

6.4 Notwithstanding anything to the contrary in this Deed, Pubco shall be entitled to delay or postpone the effectiveness of the Registration Statement, and from time to time to require a Seller (as applicable) not to sell under the Registration Statement or to suspend the effectiveness thereof, if it determines that in order for the Registration Statement not to contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements contained therein not misleading, (i) an amendment thereto would be needed to include information that would at that time not otherwise be required in a current, quarterly, or annual report under the Exchange Act and is materially prejudicial or onerous for Pubco to include or (ii) the negotiation or consummation of a transaction by Pubco or its subsidiaries is pending or an event has occurred, which negotiation, consummation or event Pubco’s board of directors reasonably believes, upon the advice of legal counsel (which may be in-house counsel), would require additional disclosure by Pubco in the Registration Statement of material information that Pubco has a bona fide business purpose for keeping confidential and the non-disclosure of which in the Registration Statement would be expected, in the reasonable determination of Pubco’s board of directors, upon the advice of legal counsel (which may be in-house counsel), to cause the Registration Statement to fail to comply with applicable disclosure requirements or (iii) in the good faith judgment of the majority of Pubco’s board of directors, such filing or effectiveness or use of such Registration Statement, would be seriously detrimental to Pubco and the majority of the board of directors of Pubco concludes as a result that it is essential to defer such filing because it would (x) materially interfere with a significant acquisition, corporate reorganization, or other similar transaction involving the Company; (y) require premature disclosure of material information that the Company has a bona fide business purpose for preserving as confidential; or (z) render the Company unable to comply with requirements under the Securities Act or Exchange Act (each such circumstance in subclauses (i) – (iii), a “Suspension Event”); provided, however, that Pubco may not delay or suspend the Registration Statement on more than three (3) occasions or for more than ninety (90) consecutive calendar days, or more than one hundred and twenty (120) total calendar days, in each case during any twelve (12)-month period. Upon receipt of any written notice from Pubco of the happening of any Suspension Event during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made (in the case of the prospectus) not misleading, each Seller agrees that (i) it will immediately discontinue offers and sales of the Sale Shares under the Registration Statement until such Seller receives copies of a supplemental or amended prospectus (which Pubco agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by Pubco that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by Pubco except for disclosure to such Seller’s employees, agents and professional advisors who need to know such information and are obligated to keep it confidential, unless otherwise required by law or subpoena. If so directed by Pubco, such Seller will deliver to Pubco or, in such Seller’s sole discretion destroy, all copies of the prospectus covering the Sale Shares in such Seller’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Sale Shares shall not apply (i) to the extent such Seller is required to retain a copy of such prospectus (a) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (b) in accordance with a bona fide pre-existing document retention policy or (ii) to copies stored electronically on archival servers as a result of automatic data back-up.

6.5 Indemnification.

(a) Pubco agrees to indemnify and hold harmless, to the extent permitted by law, each Seller, its directors, officers, employees, advisers and agents, and each person who controls such Seller (within the meaning of the Securities Act or the Exchange Act) and each affiliate of each Seller (within the meaning of Rule 405 under the Securities Act) from and against any and all losses, claims, damages, liabilities and expenses (including, without limitation, any reasonable attorneys’ fees and expenses incurred in connection with defending or investigating any such action or claim) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, prospectus included in any Registration Statement or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished in writing to Pubco by or on behalf of such Seller expressly for use therein.

(b) Each Seller agrees, severally and not jointly with any other selling shareholder under the Registration Statement, to indemnify and hold harmless Pubco, its directors and officers and agents and each person who controls Pubco (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including, without limitation, reasonable attorneys’ fees) resulting from any untrue statement of material fact contained in the Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Seller expressly for use therein. In no event shall the liability of such Seller be greater in amount than the dollar amount of the net proceeds received by such Seller upon the sale of the Sale Shares giving rise to such indemnification obligation.

(c) Any person entitled to indemnification herein shall (a) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (b) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent. An indemnifying party who elects not to assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of legal counsel to any indemnified party a conflict of interest exists between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

10

(d) The indemnification provided for under this Clause 6.5 shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director, employee, agent, affiliate or controlling person of such indemnified party and shall survive the transfer of the Sale Shares purchased pursuant to this Deed.

(e) If the indemnification provided under this Clause 6.5 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in this Clause 6.5, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Clause 6.5(e) from any person who was not guilty of such fraudulent misrepresentation. In no event shall the liability of a Seller (together with any indemnification obligation under this Clause 6.5) be greater in amount than the dollar amount of the net proceeds received by such Seller upon the sale of the Sale Shares giving rise to such contribution obligation.

7. CONFIDENTIALITY AND ANNOUNCEMENTS

7.1 Subject to Clause 7.4, Pubco and each Seller:

(a) shall treat as strictly confidential the provisions of this Deed and the other Transaction Documents and the process of their negotiation (the “Confidential Information”); and

(b) shall not, except with the prior written consent of the other parties, make use of (save for the purposes of performing its obligations under this Deed and the BCA) or disclose to any person (other than its Representatives in accordance with Clause 7.2) any Confidential Information.

7.2 Pubco and each Seller undertakes that it shall only disclose Confidential Information to its Representatives where it is reasonably required for the purposes of performing its obligations under this Deed or the other Transaction Documents and only where such recipients are informed of the confidential nature of the Confidential Information and the provisions of this Clause 6 and instructed to comply with this Clause 6 as if they were a party to it.

7.3 Subject to Clause 7.4, neither Pubco nor any Seller shall make any announcement (including any communication to the public, to any customers or suppliers of the Company) concerning the subject matter of this Deed without the prior written consent of the other parties.

7.4 Clauses 7.1 and 7.3 shall not apply if and to the extent that such party using or disclosing Confidential Information or making such announcement can demonstrate that:

(a) such disclosure or announcement is required by applicable law or by any stock exchange or any supervisory, regulatory, governmental or anti-trust body (including, for the avoidance of doubt, any tax authority) having applicable jurisdiction; or

(b) the Confidential Information concerned has come into the public domain other than through its fault (or that of its Representatives) or the fault of any person to whom such Confidential Information has been disclosed in accordance with this Clause 7.4.

7.5 The provisions of this Clause 6 shall survive termination of this Deed, and shall continue for a period of three (3) years from the date of this Deed is terminated in accordance with its terms.

8. FURTHER ASSURANCE

Each party shall, at its own cost, promptly execute and deliver all such documents and do all such things and provide all such information and assistance, as the other parties may from time to time reasonably require for the purpose of giving full effect to the provisions of this Deed and to secure for the parties the full benefit of the rights, powers and remedies conferred upon it under this Deed.

9. POWER OF ATTORNEY

9.1 From Completion and for so long after Completion as each Seller remains the registered holder of any A Ordinary Shares, it shall appoint Pubco to be its lawful attorney (the “Attorney”) to exercise all rights in relation to all such A Ordinary Shares as Pubco in its absolute discretion sees fit.

9.2 The power of attorney given in Clause 9.1 shall be irrevocable, save with the consent of Pubco, and is given by way of security to secure the proprietary interest of Pubco as purchaser of the relevant A Ordinary Shares, but shall expire on the date on which Pubco is entered in the register of members of the Company as holder of the relevant A Ordinary Shares.

9.3 For so long as the power of attorney given in Clause 9.1 remains in force, each Seller undertakes:

(a) not to exercise any rights which attach to the relevant A Ordinary Shares or are exercisable in its capacity as registered holder of the relevant A Ordinary Shares without Pubco’s prior written consent;

(b) to hold on trust for Pubco all dividends and other distributions of profits or assets received by such Seller in respect of the relevant A Ordinary Shares and to promptly notify Pubco as attorney of anything received by such Seller in its capacity as registered holder of the relevant A Ordinary Shares;

(c) to act promptly in accordance with Pubco’s instructions in relation to any rights exercisable or anything received by it in its capacity as registered holder of the relevant A Ordinary Shares; and

12

(d) to ratify whatever Pubco may do as attorney in its name or on its behalf in exercising the powers contained in this Clause 9.

9.4 Nothing in Clause 9.3 shall require any Seller to take any action (or require it to omit to take any action) where such action or omission would breach any applicable laws.

9.5 Notwithstanding the foregoing, the power and authority granted pursuant to Clause 9.1 shall in no way authorize the Attorney to:

(a) increase the obligations or alter or remove any existing rights of any Seller under the Convertible Loan Note Instrument or in connection with any securities issuable pursuant thereto (excluding the right to convert the Notes, which each Seller expressly authorizes); and

(b) subject any Seller to any non-compete, non-investment or non-solicitation or similar clause or any unlimited liability (excluding fraud by the Seller).

10. ENTIRE AGREEMENT AND REMEDIES

10.1 This Deed and the other Transaction Documents together set out the entire agreement between the parties relating to the sale and purchase of the A Ordinary Shares and, save to the extent expressly set out in this Deed or any other Transaction Document, supersede and extinguish any prior drafts, agreements, undertakings, representations, warranties, promises, assurances and arrangements of any nature whatsoever, whether or not in writing, relating thereto. This Clause shall not exclude any liability for or remedy in respect of fraudulent misrepresentation.

10.2 The rights, powers, privileges and remedies provided in this Deed are cumulative and not exclusive of any rights, powers, privileges or remedies provided by law.

10.3 This Deed shall automatically terminate and the Sale Transaction shall be abandoned immediately upon the termination of the BCA in accordance with the terms thereof. In the event of such termination, save where expressly stated to the contrary in this Deed, the rights and obligations of the parties hereunder shall be of no further force and effect, provided that nothing in this Clause 10.3 shall act so as to restrict the rights and liabilities of the parties in relation to a breach of this Deed prior to such termination. Furthermore, in the event of such termination, no Released Person (as such term is defined below) shall have any liability or any obligation of any nature to any Releasing Person (as such term is defined below) under this Deed. If the Completion does not take place concurrently with the Share Acquisition Closing, each Seller shall have the right to terminate all of its obligations under this Deed at any time by providing notice of such termination to Pubco.

11. RELEASE

11.1 Effective as of termination of the BCA, to the fullest extent permitted by applicable law, each Seller, on behalf of itself and its Affiliates (the “Releasing Persons”), hereby releases and discharges Pubco, the Company, Broadstone, the Sponsor and Merger Sub, and each of their directors, officers, employees and Affiliates (the “Released Persons”), from and against any and all actions, both at law and in equity (excluding fraud), for any “loss of opportunity or chance” or similar cause of action in connection with this Deed and the BCA.

12. WAIVER AND VARIATION

12.1 A failure or delay by a party to exercise any right or remedy provided under this Deed or by law, whether by conduct or otherwise, shall not constitute a waiver of that or any other right or remedy, nor shall it preclude or restrict any further exercise of that or any other right or remedy. No single or partial exercise of any right or remedy provided under this Deed or by law, whether by conduct or otherwise, shall preclude or restrict the further exercise of that or any other right or remedy.

13

12.2 A waiver of any right or remedy under this Deed shall only be effective if given in writing and shall not be deemed a waiver of any subsequent breach or default.

12.3 No variation or amendment of this Deed shall be valid unless it is in writing and duly executed by or on behalf of all of the parties to this Deed. Unless expressly agreed, no variation or amendment shall constitute a general waiver of any provision of this Deed, nor shall it affect any rights or obligations under or pursuant to this Deed which have already accrued up to the date of variation or amendment and the rights and obligations under or pursuant to this Deed shall remain in full force and effect except and only to the extent that they are varied or amended.

13. INVALIDITY

Where any provision of this Deed is or becomes illegal, invalid or unenforceable in any respect under the laws of any jurisdiction then such provision shall be deemed to be severed from this Deed and, if possible, replaced with a lawful provision which, as closely as possible, gives effect to the intention of the parties under this Deed and, where permissible, that shall not affect or impair the legality, validity or enforceability in that, or any other, jurisdiction of any other provision of this Deed.

14. ASSIGNMENT

No person shall assign, transfer, charge or otherwise deal with all or any of its rights under this Deed nor grant, declare, create or dispose of any right or interest in it, except to its Affiliates (an “Affiliate Transfer”). Prior to an Affiliate Transfer, the transferor shall give written notice to the other parties to this Deed.
